The FL 210 represents the fourth generation flight display over the last 7 years.  It reflects much experience and feedback from our customers in the real world cockpit environment.  With the FL 210 you get the an optimal combination of affordability, incredibly high quality bright display, and a range of capabilities unequaled by anything else you will see out there in the industry (see comparison below).  The FL 210 is most comparable to the certified panel install MFD's in the $10,000-$20,000 range but with far more capabilities, and a  far more affordable upgrade path for the future.
